2.-INTERNAL INSPECTION

For this initial inspection we will check that the OFB does not have any damage , also

if the whole cabinet comes with the internal cabling.

3.1. Installation of the Units inside the OFB according the spacedistribution of the OFBThe installation of the units in the OFB, proceed as follows:

First : Determine the position for installing the unit , for example the BBU3806 ,as shown in the figure 3.2

5.1. E1 cables and Optical fiber

Fig. 5.1.1 Route for E1 cable and Optical Fiber.

The figure 5.1 shows the route of the E1 cables and the Optical Fiber and the rule for this lay outis as follow:

E1 cable: We will use the hole marked as Spare 1 to pass through the two E1 cables to the BBU0.

The layout ofboth Cables ison the left side


14/31



Optical Fiber: We will use the hole marked as F.O. 3 to 5 to pass the 3 Optical fiber.

The Optical fiber and the E1 cable will be installed on the left side of the BBU and I will beseparated each other as the fig 5.1.1 shows.

5.2 . Transmission cables

For the E1s we will use the SPBC box as Lightning protection .The next figure shows the SPBCpanel.

For the RRU -48 VDC cables we will use the hole marked as DC LOAD 0 and we will use a 1adaptor for 1 pipe.The cables will be routed from the back to the front using the right side as the fig. 5.4 shows.

For the Grounding Bar the holes distribution will be as the following :

Fig. 5.5.1 Route for -48VDC INPUT Cables.

The -48VDC INPUT cables will be routed by the left side and we will use the hole marked as DCIN 0. To do that we will use a 1 terminator for 1 flexible pipe. As the fig 5.5.1 shows.

Note: We can use the cable BLACK and BLUE cable from china if the distance betweenthe OFB and the POWER SOURCE equipment is less than 18 m.

5.6. . ALARM CABLESThe alarm cable or the BBU is an R J45 connector which has three cablepairs, and each pair is connected as the pictures show.

6. USED HOLES OF THE OFB

Fig. 6.1 Used holes of OFB.

SPARE 0 : We will use a 1 terminator and 1 flexible pipe to pass the -48VDC Cables.SPARE 1 : We will use a 1 terminator and 1 flexible pipe to pass the E1 Cable.

Fig 6.2. Connection to 1 pipeA: Connector -tube pipe-connector -adapter to 1

B: Adapter to 1

DC LOAD 1 to 3: We will use a 1terminator and 1 flexible pipe to pass 3 -48VDC RRU cables.NOTE: IN SOME CASES IT COULD BE CHANGED ACCORDING TO RRUS LOCATION.

F.O.3 to 5 : We will use a 1 terminator and 1 flexible pipe to pass the 3 Optical Fiber. NOTE: IN SOME CASES IT COULD BE CHANGED ACCORDING TO THE RRUS LOCATION.

OFB ON THE WALL

When the OFB need to be installed on the wall, we will consider the following

-RRUS in the same position:

E1

OFB DC

CPRI

RRU DCRRU DC

RRURRURRU

On tower

OFB

Ladder

Wall

Fig. 7.1 RRUs installed in the same tower.

.With this scenario the RRUs are in the same tower or in the same pole and we can run 3-48vdccables inside of 2 pipes 1 and the 3 fiber cables inside of a pipe 1:

We will use the distribution if the RRU are located in different positions .

-RRUS Distributed in different position:


23/31



Fig. 7.2 RRUs installed in different position. The figure 7.2 show the installation way when the RRUs are installed in different position.

We will use the boxes to distribute the optical and the power cables from the OFB to the RRU,and inside the boxes we can run the cables to different directions as the fig 7.3 shows.
